Abstract
Provided herein is a process for treating water containing natural organic matter (NOM) to produce potable water, the process comprising a plurality of oxidation steps for degrading NOM, wherein the plurality of oxidation steps comprise one or more of subjecting water to inorganic oxidant, oxygenation, catalytic oxidation, and catalytically advanced oxidation (CAO). Also provided herein is a process for treating water for producing potable water, the process comprising a plurality of oxidation steps; wherein the plurality of oxidation steps comprise one or more of fragmentation of NOM with ozone, homogeneous catalytic oxidation with ozone, and catalytically advanced oxidation using granular metal oxide catalyst.
Claims (14)
- CLAIMS 1. A process for treating water containing natural organic matter (NOM) to produce potable water, the process comprising a plurality of oxidation steps for degrading NOM, wherein the plurality of oxidation steps comprise one or more of subjecting water to inorganic oxidant, oxygenation, catalytic oxidation, and catalytically advanced oxidation (CAO).
- 2. A process according to claim 1, further comprising the step of subjecting the water to biological filtration, such as biological activated carbon (BAC) filtration.
- 3. A process according to claim 1 or claim 2, further comprising the step of contacting water with granular activated carbon (GAC) for removal of remaining organic matter and for removal of potentially toxic fraction resulting from degradation of organic matter.
- 4. A process according to any one of claims 1 to 3, further comprising treating water with chlorine to provide a residual disinfectant level in the water.
